See the solutions to these problems just after the percentage calculator below.

Here are the solutions to the questions stated above:

Always use this formula to find a percentage:

^{%} / _{100} = ^{Part} / _{Whole} replace the given values:

^{1.8} / _{100} = ^{Part} / _{5/9}

Cross multiply:

1.8 x 5/9 = 100 x Part, or

1 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{1} / _{100} = 0.09

Use again the same percentage formula:

^{%} / _{100} = ^{Part} / _{Whole} replace the given values:

^{%} / _{100} = ^{1.8} / _{5/9}

Cross multiply:

% x 5/9 = 1.8 x 100

Divide by 5/9 and get the percentage:

% = ^{1.8 x 100} / _{5/9} = 324%
